Veset & extending pill cycle

7 November, 2006


I got married two months ago and started taking the pill 3 months before my wedding. I didn't establish a veset kavua though.
We are going away this week so I have extended my use of the pill – if not I would have stopped taking the pill on Sunday but instead am continuing another cycle without a break.
What do I do about my vesatot this month?


Mazal tov on your recent wedding!

There are different opinions on how hormonal regulation of the cycle effects vesatot.  If you have been consulting with your local rabbi, you should turn to him with this question for a consistent ruling.  The following answer is based on the rulings of our rabbinic supervisor, R Yehuda Henkin: 

If you have established over the past three cycles (or more) that you do not bleed until after stopping active pills, then you will not observe any veset days until after you have stopped active pills.  This is the case even without a veset kavua and even on an extended cycle.

You will observe veset days beginning from the minimum interval from which you usually begin a blood flow after cessation of the pill.  In other words, if for the past three cycles at least 'x' days elapsed between cessation and onset of blood flow, then you would treat the day after day 'x' following cessation of the pill this cycle as a veset day and continue to act as on a veset day until the onset of bleeding.  If you do not begin bleeding within the next few days, you should seek rabbinic and medical advice.

We hope this is clear.  Please write back with any further questions.
